SAFETY
e following are important safety guidelines every diver should adopt before diving
in a dry suit:
› Complete a dry suit diving course with a certied instructor and from an industry
recognized training agency.
› Always dive with a buoyancy compensator.
› Become familiar with all of your equipment before diving.
› Practice dry suit diving skills in safe conditions until condent of your ability. Ensure
that your buddy/partner is completely familiar with and understands all functions of
your dry suit.
› Weight should be added to achieve neutral buoyancy with an empty tank. Do not add
more weight than required. You should be able to complete a 5-minute safety stop at 3
meters (10 feet), neutrally buoyant with a tank containing around 30 bar (500 psi) or
less.
› Inspect the main zipper, seals and valves for damage before each dive.
› Perform regular preventative maintenance on the suit, valves, main zipper and seals.
› Only allow qualied technicians to perform service on the dry suit.
› Use tender line when diving in demanding conditions.
› Understand your personal diving limitations and do not exceed them.
APPLICATION
is dry suit is designed for diving in various environments and can be used in cold,
icy water or in warm water by increasing or decreasing the insulation value of
the undergarments.
Rinsing the dry suit thoroughly with fresh water and drying is recommended after diving
in very salty or mineral rich waters.
A qualied and certied diver may use this dry suit to a maximum depth of 60 meters.
For this dry suit system, we recommend the use of air for the ination gas.

DIVE RITE 901 SERIES | INSTRUCTIONS FOR USE Page 5
Main zipper
We oer our dry suits with a YKK Aquaseal tm. main zipper as standard. A metal Dynat tm.
main zipper is optional. e dry suit is available with a front main zipper (FZ) placement as
standard and has the option of a back main zipper (BZ) placement.
An optional relief zipper can be provided with either a Aquaseal tm. or Dynat tm. zipper.
SERVICE OF MAIN ZIPPER
Models BZ and FZ have a cover ap to protect the main zipper. With proper service and
cleaning the main zipper will last for several years, even under heavy use. After every use it is
very important to clean the main zipper from dirt and other debris. Normally, rinsing with
clean FRESH water is enough. When the main zipper is dry, it must be lubricated with the
proper lubricant. Do not bend the main zipper.
Neck and wrist seals
Our durable latex neck and wrist seals will keep water out even when exed and stretched.
Standard dry suits are provided with a detached hood (SH) with neck warmer.
Neck seals are also available in neoprene, silicone, or latex with modular Quick-Change
Solution.
As an option you can also select an attached hood (AH) made of 5mm neoprene with latex
neck seal for instead of a detached hood (SH).
Wrist seals are also available in silicone or latex with modular Quick-Change Solution.
Attached gloves (AG) are also optional.
CHECKING THE SEALS
When trying on the dry suit, check for proper tment of the neck and wrist seals. e
seals should feel tight when they are dry and there should be no gap between your skin and
the seal. If you are unsure about the size, ask for guidance from a knowledgeable retailer. If
the seals are too tight, they may be trimmed with sharp scissors. Make sure that the edge is
smooth after trimming to avoid leakage.
DRY SUIT

DIVE RITE 901 SERIES | INSTRUCTIONS FOR USE Page 6
Ination and exhaust valves and low-pressure inator hose
Every dry suit system is delivered with ination and exhaust valves.
As an option you can also choose a relief valve (RV) for your dry suit.
A low-pressure inator hose is also included with this dry suit system.
STORAGE AND MAINTENANCE
Store the dry suit so that the seals are dry, cool, and out of direct sunlight. To preserve the
seals before long term storage, dust them inside and out with pure talcum powder.
POSSIBLE ALLERGY RISK
A small percentage of people have an allergic reaction to natural latex, the material from
which the neck and wrist seals of some models are manufactured. is allergy can range
from mild to severe skin rash and itching. It is the responsibility of the user to determine
beforehand if he or she has a latex allergy, or to recognize it during use and discontinue using
the suit until the problem can be rectied. is usually means removing the latex seals, and
installing new seals made of an alternate material.
Before purchasing or using a dry suit with latex seals, make sure that you are not
allergic to latex.

DIVE RITE 901 SERIES | INSTRUCTIONS FOR USE Page 7
FITTING THE DRY SUIT
Carefully read the user’s and service guides and check your dry suit so that you understand
it fully.
First remove any watches, rings, or jewelry that could tear the wrist seals. Please note that
Dive Rite 901 series dry suits require the use of an additional undergarment to provide
adequate thermal protection. e thickness of the undergarment depends on your diving
environment. To ensure a good t, it is recommended that you try the dry suit on while
wearing the thickest undergarments that you intend to use with the dry suit. Make sure that
you can raise both hands over your head, touch your toes, and squat to your knees without
restriction while wearing the dry suit and undergarment.
If you will be using the dry suit with back-mounted cylinders, ensure that you can easily
reach your valves.
NOTE: Proper t of the dry suit is very important. Too loose of a t will allow such hazards
as excessive air in the dry suit, dicult buoyancy control, and if the legs are too long, the
boots can slip o the divers’ feet. Seals that are too loose will leak. Too tight of a t can
result in restriction of blood ow causing loss of feeling in the extremities or lack of oxygen
to the brain.
WARNING: Do not use a dry suit that is too large or too small.
Before using this dry suit, verify the proper function of the ination and exhaust valves.
First, attach the low-pressure inator hose to the ination valve by pulling back on the col-
lar, inserting the ination valve stem into the hose coupling, and releasing the collar. Pull
gently on the hose to ensure that it is locked onto the valve stem. Next, push the ination
button briey to ensure the valve is working properly. Gas should enter the dry suit when
the button is pressed, partially inating it, and stop when the button is released. Once
proper function of the ination valve has been veried, disconnect the low-pressure inator
hose by pulling back on the collar and removing the hose from the valve stem. To check
proper function of the exhaust valve, turn the valve counterclockwise to open it completely
and crouch to your knees. is should force air out of the dry suit, and you should hear air
escaping from the exhaust valve.

DIVE RITE 901 SERIES | INSTRUCTIONS FOR USE Page 8
DONNING THE DRY SUIT
› First, remove any watches, rings, or jewelry that could tear the wrist seals.
› Check your dry suit to ensure that it is in good condition.
› Check that the main zipper is in good condition and completely open before donning.
e main zipper should be free of debris and should be visually inspected for tears or
other failures prior to each use. Ensure that the main zipper is properly lubricated.
› Check the condition of the neck and wrist seals. Seals should not be gummy or have
any cracks or tears in the material. If using a modular Quick-Change Solution, ensure
that the seals are properly secured to the dry suit.
› Check the valve retaining rings (on the inside of the dry suit) and the ination and
exhaust valves to ensure that they are in good condition.
› Step into the dry suit and pull the dry suit up to your chest.
› Put your hands into the sleeves and check that the wrist seals are tight on your wrists.
› Pull the neck seal over your head.
WARNING! Rough handling can cause damage to the wrist and neck seals.
› Close the main zipper with a steady pull of the slider while ensuring that nothing be-
comes pinched between the main zipper’s teeth. Conrm that the zipper is fully closed.
Next, close the cover ap zipper fully. When using FZ or BZ styles, ask your diving
buddy to ensure the zipper is fully closed.
› In models without cover aps, close the main zipper with a steady pull of the slider
while ensuring that nothing becomes pinched between the zipper’s teeth and conrm
that the zipper is fully closed.
› Open the cylinder valves according to the manufacturer’s instructions and make sure
that the cylinders are full of air.
› Don the equipment according to the manufacturer’s instructions.
› Connect the low-pressure inator hose, following the instructions provided previously,
to the ination valve on the chest of the dry suit.
› Press the ination valve briey 2-3 times to verify that it is functioning correctly.
› Squat down and press on the dry suit to verify that the exhaust valve is functioning
correctly.

DIVE RITE 901 SERIES | INSTRUCTIONS FOR USE Page 9
DOFFING THE DRY SUIT
› Disconnect the low-pressure inator hose from the ination valve and do the dive
equipment.
› Open the cover ap zipper fully and then the main zipper completely by pulling the
slider straight up over your shoulder. Be careful not to damage the teeth of the cover
ap zipper. For models that do not have a cover ap just open the main zipper carefully.
› Pull the neck seal carefully over your head. Be careful with your ngertips and nails as
they can easily damage the seal.
› Pull hands out of the sleeves turning them inside out. Use the thumbs to remove the
seals.
› Remove your feet from the dry suit and service the suit according to instructions.
› Close the exhaust valve.
› Don the rest of your equipment according to the manufacturer’s instructions.
› Always follow all applicable safety regulations.

DIVE RITE 901 SERIES | INSTRUCTIONS FOR USE Page 10
Safety precautions before using your suit

BEFORE DIVING

DIVE RITE 901 SERIES | INSTRUCTIONS FOR USE Page 11
Pre-dive inspections
Before every dive, make sure the dry suit is in good condition:
› Visually inspect all of the materials and accessories, including fabric, seals, boots,
ination and exhaust valves, etc. Ensure, that there is no damage.
› Check that the ination and exhaust valves are securely attached to the suit and that
they are functioning properly.
› Check that the low-pressure inator hose and ttings are intact, undamaged, and
properly connected.
› Check that the main zipper is in good condition and properly lubricated.
WARNING - DO NOT
¤Exceed the maximum depth to which you are currently certied.
¤Use the dry suit in toxic or hydrocarbon-rich environments.
¤Use the dry suit as a buoyancy-lifting device.
¤Use the dry suit without a separate buoyancy control device.
¤Use ination gases other than air (except argon and only if you are
qualied).
¤Use the dry suit with any weight harness or other weight system that is
not equipped with a quick-release system.
¤Overexert yourself while wearing this dry suit.

DIVE RITE 901 SERIES | INSTRUCTIONS FOR USE Page 12
POSTDIVE INSPECTIONS
› Check the materials of the dry suit carefully, including seals, boots, and ination and
exhaust valves.
› Repair any damage immediately or send the suit to Polarsafety for repair.
Inspection intervals
In addition to the checks listed above to be performed before and after every dive, the valves
should be inspected and serviced on an annual basis. If the dry suit has been stored for a
while, the dry suit must be inspected by the manufacturer or an authorized service technician
before the rst dive.
WARNING:
DO NOT DIVE IF YOU NOTICE ANY DAMAGE TO YOUR DRY SUIT!
DIVING
› Make sure that you have donned all of your equipment correctly and carefully.
› Close the exhaust valve and add some air into your dry suit before entering water.
› While in water, check the function of all of your equipment. Open the exhaust valve
and lift your left arm so that the exhaust valve is raised to the highest point. Air should
escape the from the exhaust valve and you can start descending.
› As you descend it will be necessary to add air into the dry suit to prevent it from
squeezing your body. Only add enough air to the dry suit to maintain comfort and
ease of mobility. Excessive air in the dry suit can make it dicult to maintain proper
buoyancy and trim.
› While diving at the desired depth it should not be necessary to regulate the exhaust
valve.
› As you ascend, the exhaust valve will automatically release the excess expanding air out
of your dry suit. Ascend slowly at a rate not exceeding 10 m/min. Raise your left arm so
that the exhaust valve is at the highest point to allow the expanding air to escape.
› When you reach the surface close the exhaust valve completely (clockwise) and add
some air into the dry suit.
› To avoid being stuck in an upside-down position, do not allow excessive air to
accumulate in the dry suit and maintain proper trim. Raise your left arm so that the
exhaust valve is at the highest point to allow the excess air to escape.

DIVE RITE 901 SERIES | INSTRUCTIONS FOR USE Page 13
Service of the suit
› Store your dry suit on a broad hanger in a cool, dry place and out of direct sunlight.
Do not store the dry suit in a room with electric motors or other equipment that
produce ozone.
› Keep the dry suit clean and rinse it thoroughly after each use.
› If the dry suit is excessively dirty it can be hand washed in a 40°C mild detergent solu-
tion, rinsed thoroughly, and allowed to dry completely. Make sure that the inside of the
dry suit is also allowed to dry completely. Do not store the dry suit in the provided dry
bag if the dry suit is wet or damp.
› Apply talcum powder to the latex seals of the dry suit after each use or wash. Lubricate
the zipper following manufacturer’s instructions. Keep the zipper clean and do not store
the dry suit with the zipper bent.
› Keep the dry suit so that the face seal of the hood will not become creased.
›WARNING!
Never use gasoline, petroleum, or similar solvents for cleaning the dry suit.

DIVE RITE 901 SERIES | INSTRUCTIONS FOR USE Page 14
WARNINGS OF THE RISKS
Dry suit diving, as with any other aspect of advanced SCUBA diving, carries a degree of
inherent risk, including:
TEMPERATURE CONDITIONS
Temperature conditions above and below the surface aect the use of dry suit. e dry suit
itself does not provide any thermal protection. Dierent thicknesses of undergarment can
be selected to adjust the insulation to match your diving environment. e suitable working
temperature for the dry suit is from -2°C to 30°C with the appropriate undergarment.
WARNING: Test the undergarment combination together with the dry suit before the
actual dive if the temperature conditions are dierent from your typical diving
environment.
HYPER/HYPOTHERMIA
Dry suits are often used in extreme temperature conditions, where there may be combinations
of cold surface conditions and cold water, or hot surface conditions and cold water. To avoid
over heating or becoming chilled, it is important to know your own personal thermal safe
range. While a dry suit and warm undergarment provide excellent thermal protection, they
are still limited, and the amount of time that you can safely stay in the water is based on water
temperature and condition, workload, and your own body type. Hyperthermia is the
overheating of the body core to unsafe levels. Hyperthermia while using a dry suit is most
often experienced during surface intervals in hot weather, or during periods of excessive
workload in warm, shallow water. Hypothermia is the cooling of the body core to unsafe
levels.
WARNING: Learn your own limitations and learn to recognize discomfort as a sign of
danger. Both hyperthermia and hypothermia can be harmful or even fatal.
LOSS OF THERMAL INSULATION AT DEPTH
Dry suits provide thermal insulation by creating an air space between the diver and the
water. e dry suit material itself does not provide much insulation value. When planning an
extended range dive, divers must account for the additional time spent at depth and add suit-
able undergarments for protection against thermal loss.
WARNING: Always pay attention to thermal loss at depth when planning the dive.

DIVE RITE 901 SERIES | INSTRUCTIONS FOR USE Page 15
CHANGE OF BUOYANCY WITH DEPTH
e dry suit´s material is like a membrane and lacks a closed cellular structure, so the dry suit
itself does not change buoyancy with depth. However, the air trapped within the dry suit by
the undergarment will be compressed during descent and the diver compensates for this by
adding air to maintain the volume of air inside the dry suit. During ascent the air inside the
dry suit will expand and the diver must vent air from the dry suit to prevent excessive buildup
of air inside the dry suit.
WARNING: To maintain the proper volume of air in the dry suit, add and vent gas as
required. It may also be necessary to adjust the exhaust valve periodically.
FITTING THE DRY SUIT
Proper t of the dry suit is very important. Too loose of a t will allow such hazards as exces-
sive air in the dry suit, dicult buoyancy control, and if the legs are too long, the boots can
slip o the divers’ feet. Seals that are too loose will leak. Too tight of a t can result in restric-
tion of blood ow causing loss of feeling in the extremities or lack of oxygen to the brain.
VAROITUS: Do not use a dry suit that is too large or too small.
INFLATION GASES
Air is the recommended ination gas. Properly trained divers can use argon. Do not use gas
mixes with elevated oxygen levels, or gasses containing helium (Trimix, etc.).
WARNING: Use air for ination. Only properly trained divers may use argon and oxy-
gen enriched gas.
ALLERGIES
In addition to the possible allergic reaction to latex used in the neck and wrist seals, a small
percentage of people are known to experience allergic reactions to neoprene. Be sure to
determine you do not have these allergies or contact your retailer to nd out about alternative
options. Always use the dry suit with an undergarment.
WARNING: Before diving, be sure that you will not have an allergic reaction to any of
the dry suit’s materials.

DIVE RITE 901 SERIES | INSTRUCTIONS FOR USE Page 16
Maintenance, repair and modication
It is not within the scope of this manual to provide complete and detailed repair instructions
for all situations that may occur.
Cleaning, disinfection and decontamination
After each use:
Rinse the outside of the dry suit with clean fresh water. Wipe seals clean with clean fresh
water. Rinse valves with clean fresh water. Hang the dry suit upside down and allow to dry
completely.
If the dry suit is wet on the inside:
Clean the inside with clean fresh water, or a disinfectant solution to prevent bacterial growth.
Latex seals:
Lightly dust with talcum powder (supplied in the maintenance kit).
Degreasing:
If the dry suit is exposed to oil or grease, clean with a mild grease cutting detergent and a soft
brush. Rinse with clean fresh water.
WARNING: Never use gasoline, petroleum or similar solvents for cleaning the dry suit.
Decontamination:
Recreational divers should take care to avoid exposure to contaminated water and environ-
ments. Professional, commercial, rescue and military divers who may be forced to dive in
contaminated conditions must identify the contaminant and take appropriate steps to remove
the contaminant from the dry suit before it can be used again.
Testing the dry suit
¤Close all the holes of the dry suit and ll the suit with water.
¤Mark all leaks with a water-resistant marking pen.
¤Allow the dry suit to dry completely
MAINTENANCE

DIVE RITE 901 SERIES | INSTRUCTIONS FOR USE Page 17
Modication
Dry suit can be modied in several dierent ways. To ensure the safety of your dry suit,
always contact your dealer or manufacturer prior to modication.
Packing
e dry suit comes complete with ination and exhaust valves, low-pressure inator hose,
repair kit, and a 5mm neoprene hood (if ordered with a detached hood) and is packed in a
dry bag. Do not store the dry suit in the dry bag if the dry suit is not completely dry.
